Q1:

Assertion (A): The inductance of an iron cored solenoid is not constant. Reason (R): BH curve of an iron specimen is non-linear.

A Both A and R are true and R is correct explanation of A

B Both A and R are true and R is not the correct explanation of A

C A is true but R is false

D A is false but R is true

ANS:A - Both A and R are true and R is correct explanation of A

Since B-H curve is non-linear, the inductance of iron cored solenoid is not constant.
